Each part matters in the process of assembling parts just one part missing can lead to a failure of the whole project. Then what need to pay attention in designing assemblies? Generally, typical assemblies in CNC machining include housing, chassis, shaft, bracket and so on. Today let’s talk about it.
• The Selection of aluminum alloy materials
The most commonly used aluminum alloys are 6061-T6 and 7075.With the popularity of Energy conservation and environmental protection, soft aluminum elements are highly malleable and recyclable which make it a best choice for mechanical purposes. Conversely, if the aluminum elements are mixed with other elements such as magnesium, silicon, copper and zinc, they can form to aluminum alloy after the heat treatment. The aluminum alloy has good strength, super hard aluminum alloy can reach to 600 Mpa, and the tensile strength of normal hard aluminum alloy is 200-450 Mpa. It has been widely used in manufacturing.
6061-T6 is corrosion resistant type with good strength and uniformity. Among the aluminum parts, 6061-t6 are mainly used to materials machining, it’s not easily deformed and almost none tolerance problems. During the post-machining process, a great oxidation post treatment effect can be achieved.
The 7075 aluminum plate is of Al- zn-mg - Cu.Good series Super-hard aluminum. With good mechanical property and wear resistance, it can be easily machined. It also has good anodic oxidation after treatment and also anti corrosive and oxidation resistance. 7075 aluminum is a typical material used in aviation industry with complex structure and high precision.
• CNC aluminum machining
CNC aluminum machining is one of Wayken Rapid's main services. We have experienced design teams and programmers can efficiently to do every project review. With accurately assessment of the costs, plasticity and complexity to ensure perfectly fit your design. In 2017, we have new 5 Axis machining center in our factory, high efficiency and precision enable us to provide the best service to our clients. One time work piece, high precision in the complex space surface work, modern molding such as auto parts and aircraft structure parts can be perfectly machined. Based on your CAD data, we can cut the shape of any material. No matter how many parts your assembly is composed of, we can produce high precision metal parts fast and meet the strict tolerance standards in the same time. Surface treatment machining is commonly used in aluminum including oxidation, secondary oxidation, surface drawing, sand blasting and high gloss, spraying, and printing.
• How to carry out the original verification and assembly inspection after processing?
Original verification and assembly inspection are the most critical steps in the whole machining work. The former is to measure the width, the size and height of each part. For metal parts, especially the diameter, diameter of pin or the diameter and inner diameter of the shaft should be put in place to ensure the rotation of the tightness. According to the requirements of the customer, some are ask for rotating it 180 degrees or internal 360 rotations. Due to different demands, the standard of assembly inspection shall be based on the 3D data provided by the customer. The gap and run-in place between parts should be checked carefully.
